INNER TUBE VALVE.

' ings, wherei To all "wit-0;")? Be it l'iflO citizen. of i' Youngstown State or (line, and useful Valves; and 1 lowing to he scription of th. able others ski. pertains to This in Y'Vith the the inventio combinations will he here claimed and iilu 4 drawings, in iv Figure l my improved the val e in angles to s the d vi line 4 4- ot Reform 5V ignate similar I views, the-nut '1 tube or easing xvii as shown at 'l l BEG upper or outr end it riorly threads Inent by a el the tube afte in is inflated. casing of as shown at largedvalve in the valve w? securely mg? same.

The upper 3'; 10 is provided,

ged as shown at 18 to provide 'houlder 19 forming a valve 986 to be hereinafter made v seat being located at a point so on; the center of the tube 10 near end While the innerend of the tube .readed and formed with tvvo opposite longitudinal grooves 65 Y which the air is fed into the to be inflated in a manner to be made apparent. It is of course that the bore 20 or the portioro e is of similar diameteras the l n carrying out my invention, v-e stem which 'is -considdiameter than the porie of the tube or casing 10 {{QCl metallic valve head u is formed of metal comactetl by a relatively thick i which is adapted to en lder 19 to prevent the escape ter the tire is inflated. The valve ere. s between the enlarged portions and 26 or me bore of the valve tube or 16 being snugly fitted therein and the upper end of its stem 22 formed ,1 longitudinal slot 24' which is slid-.8

"*ed over a transverse retaining einlecl through the enlarged portube 10 serving to guide the A during its operative movement. 1 end. of the stem 22 carries a 1. member 26 which when moved :l-ot 2 iprevents displacement .BTll-WlldlY While the end wall 27 limits the outward displacevalve in contact With the shoulient play being allowed to petr seating the valve. It will thus at when it is desired to inflate mcr tube or tire, the cap 14 is removed pump eonnectxed with the thread 13 ated, air being forced through the -nd moving the valve 14 inwardly he inlet portion of the feed slots 21 by the numeral 28 as shown 1n the drawings, thus permitting the beyond the valve and through and consequently into the tire or hen the tire or tube is inflated to 3 degree, the pump is removed, fiiliitilij pressure from the valve the air Within the tire or I 3 on the valve to force it into contact with the shoulder 19 guided by the engagement of the pin 25 within the slot 24 so as to prevent escape of the air. It will thus be seen that the air fed to the tire or tube which is inflated operates to automatically open the feed valve and when the supply means or pump is removed, the said valve will automatically move to aclosed position and prevent the escape of the air, thereby avoiding the necessity of employing springs which icomp lieate the structure and often get out of order.

The valve and its stem 2-2 are fitted within the tube or casing 10 from its inner end and the catch 26 prevents it frolndropping out of place. 4

" I claim:

A valve of the class described comprising a casing adapted for attachment to a wheel rim, 'said casing having one end open and provided with a counter-bore, the main bore of the casing terminating at a point intermediate of the ends of the casing, and the casing being provided with a reduced bore extending from the inner end of, the main bore to the end of the casing, the face of the main bore being provided with a plurality of feed grooves, a valve having a cushion head and a stem slidable in the reduced bore, the inner end of the main bore forming a valve seat, the upper end of the valve stem being slotted, a transverse re taining member engaged in the wall of the- JOHN s.
